Key Features

• EPDM construction for coolant-hose durability
• Black finish for a clean OE-style appearance
• 1 5/16 in. inside diameter at both ends
• Single I.D. hose design for curved routing
• Protective sleeve included; no heat shield
• Built to SAE J20R4 Class D-1 and SAE J1684 Type EC specifications

Product Details

This Dayco curved radiator hose is engineered for coolant transfer in applications that require a formed hose profile and consistent inside diameter. The hose measures 1 5/16 inches at both ends and uses EPDM rubber for resistance to heat and coolant exposure in everyday cooling-system operation. The protective sleeve adds an extra layer where routing passes near surrounding components. Dayco 72109 is a direct service option for vehicles including Mitsubishi Lancer, Mitsubishi Eclipse, Chrysler Sebring, and Dodge Stratus, with fitment coverage that also includes select Mitsubishi Lancer upper hose applications. This part cross-references ACDelco (e.g., 24453L, 24673L) for the same application.

Installation Notes

Verify hose routing, end diameter, and position before installation. Some Mitsubishi Lancer applications require the hose to be cut on both ends, so measure carefully and trim only as needed for the specific vehicle layout. Inspect clamps, necks, and adjoining cooling-system components for wear before installing the new hose.
